Considering global warming and other unfortunate processes, one would think that everything is going downhill regarding our beloved planet. But, it seems that things are not quite like that.
It’s been just reported that scientists at NASA said that the hole in the Earth’s ozone layer has shrunk to the smallest size that’s been recorded since it was first detected.
According to a press release coming from the space agency, the whole which has been naturally growing and shrinking every year due to the temperatures in the Arctic has now been able to shrink to its early low at the end of September and the beginning of October, and it surpassed the lows registered in the past years.
NASA reported that the hole is now 3.9 million square miles, and this is the lowest level on record since the hole had been first detected back in 1982.
Scientists at NASA’s headquarters in Greenbelt, Md., explained that the change in temperatures that triggered warmer air in the Arctic, contributing to ozone gap shrinkage, was related to a “normal yearly phenomenon and not climate change.”
This is great news for ozone in the Southern Hemisphere
“It’s great news for ozone in the Southern Hemisphere,” according to Paul Newman, chief scientist for earth sciences at the facility.
He continued and explained this: “But it’s important to recognize that what we’re seeing this year is due to warmer stratospheric temperatures. It’s not a sign that atmospheric ozone is suddenly on a fast track to recovery.”
“This year, ozonesonde measurements at the South Pole did not show any portions of the atmosphere where ozone was completely depleted,” explained Bryan Johnson, an atmospheric scientist.
It’s also worth noting that the dangerous hole in the ozone layer is contributing to increased negative effects from the ultraviolet rays all over the globe.
